BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a joining structure of an outer wall material for covering an outer surface of a structure by joining in a plane direction.

[0002]

2. Description of the Related Art In the past, decorative boards and the like for lining the outer surface of a building have been attached by laying lithographic plates made of stone, concrete, or the like and joining them in the plane direction. These lithographic plates are joined by laying a rubber mat or the like on a flat surface plate set in a factory and arranging several lithographic plates to be joined on the rubber mat. A plate for retaining the dowel pin such as a steel plate is interposed between the two plates, and the dowel pin is provided in both the dowel pin insertion hole penetrating the plate for retaining and the end face to be joined of the planographic plate. By inserting a dowel pin and injecting an adhesive between the lithographic plates and the dowel holes in this state, the lithographic plates are joined to each other. Then, when the joining of several lithographic plates is completed, the lithographic plates are transferred to a work position and set at a predetermined position.

[0003]

However, in the case of the above-mentioned joint structure, the joint force between the lithographic plates is insufficient, and there have been problems such as reworking of the work. That is, the joining force between the two lithographic plates depends on the adhesive force exerted by the adhesive between the lithographic plates and between the dowel holes and the dowel pins, but the dowel pins are inserted into both the dowel holes to join the lithographic plates. If the distance between the joining end faces is set at a predetermined interval, it is difficult to fill the dowel hole with the adhesive, and the adhesion may be insufficient.

In view of the above problem, a method of applying an adhesive in advance to the end of the dowel pin before insertion into the dowel hole is conceivable, but this time it is inconvenient to adjust the position such as the installation interval. The workability deteriorates and it does not become a fundamental solution.

The present invention has been made in view of the above-mentioned problems, and has as its object to provide a joint structure of an outer wall material in which the filling property of the adhesive is facilitated to improve the workability and the work accuracy. Things.

[0006]

In the joint structure of the outer wall material according to the present invention, a stop plate projecting to the back side of the outer wall material is sandwiched between the joint end surfaces of the outer wall material, and the dowel pins penetrate the stop plate. Means for solving the above-mentioned problem is to insert into dowel holes formed in both joint end faces, and to further fill an adhesive from an adhesive injection hole communicating with a deep end of the dowel hole formed in the outer wall material and one surface of the outer wall material. And

[0007]

According to the joint structure of the outer wall material of the present invention, it is easy to fill the adhesive into the dowel hole by injecting the adhesive from the adhesive injection hole, thereby improving the workability. In addition, the dowel pin and the dowel hole can be securely bonded to each other, and rework is reduced.
